(Tailscale co-founder) Everyone at tailscale agrees 100% with all your comments here. We're eager to someday have a chance to stop optimizing NAT traversal so that we can make magic DNS work. But we also know we have to get the core routing near-perfect before we start adding more features. I'm guessing ZeroTier feels the same.

As someone who's been following tailscale's development, I'm curious to what you mean by core routing? Isn't routing P2P? Or, do you mean routing via DERP tunnels or TURN relays when P2P is a no-go? If so, what really are some key challenges here?
